title: '`href` Interpolation Failed'
---
## Why This Error Occurred
Somewhere you are utilizing the `next/link` component, `Router#push`, or `Router#replace` with `href` interpolation to build dynamic routes but did not provide all of the needed dynamic route params to properly interpolate the `href`.
Note: this error will only show when the `next/link` component is clicked not when only rendered.
**Invalid `href` interpolation**
```jsx filename="blog-link.js"
import Link from 'next/link'
export default function BlogLink() {
return (
Invalid link
)
}
```
**Valid `href` interpolation**
```jsx filename="blog-link.js"
import Link from 'next/link'
export default function BlogLink() {
return (
Valid link
)
}
```
## Possible Ways to Fix It
Look for any usage of the `next/link` component, `Router#push`, or `Router#replace` and make sure that the provided `href` has all needed dynamic params in the query.
